RV Solar System – INSTALLATION & COSTS

 

Introduction

In this article, we delve into the details of installing a solar system on an RV. We’ll cover the components involved, the cost of installation, and some key considerations for those thinking of taking on this project.

 

Components and Costs

Solar Panels

The solar panels are the primary component of the system. For this installation, we used four Renogy solar panels, each costing $199, totaling $800. The panels were mounted on the roof without drilling holes, using special brackets with super-strong 3M adhesive tape, ensuring a secure and damage-free installation.

 

Wiring and Mounting

Wiring is crucial in connecting the solar panels to the battery system. The wires were run through the refrigerator vent to avoid drilling more holes into the RV. Additional costs included a wiring distribution box and various knickknacks such as sealants, circuit breakers, and heavy-duty cables, which amounted to approximately $1,700.

 

Batteries

We opted for four Battle Born lithium batteries, each costing about $950. These batteries are lighter, last longer, and offer more power output compared to traditional lead-acid batteries. The total cost for the batteries was $3,800.

 

Inverter and Charge Controller

A Victron 3000-watt inverter was installed to convert the solar energy into usable AC power, costing around $1,200. Additionally, a solar charge controller, essential for regulating the voltage and current from the solar panels to the batteries, was installed for $300.

 

Additional Equipment

Other necessary components included a battery monitor display ($200) and a progressive industry surge protector for $300. The DC to DC charger, costing about $300, was installed to protect the alternator in the truck from being overdrawn by the lithium batteries while driving.

 

Installation Process

The installation process involved several steps:

  • Mounting Solar Panels: Placed towards the rear of the RV for even weight distribution.
  • Running Wiring: Routed through the refrigerator vent to connect the panels to the battery system.
  • Installing Interior Components: Batteries, inverter, and charge controller were placed at the front of the trailer to avoid adding unnecessary weight to the rear.
  • Switches and Fuses: Installed to manage and protect the electrical system.

 

Labor and Time

The entire installation process took approximately 50 hours of labor. Given the complexity of the wiring and the need for precise installation of various components, it is advisable to seek professional help unless you have a detailed knowledge of electrical systems.

 

Total Cost

The total cost for this solar system installation, including all components and knickknacks, was around $8,800. This does not include labor costs, which can add significantly depending on the complexity and specific requirements of your RV.

 

Conclusion

Installing a solar system in your RV can be a significant investment, but it offers the advantage of sustainable and silent power, ideal for boondocking and off-grid camping. The cost will vary based on your specific needs and the components you choose. For those not confident in their DIY skills, hiring a professional installer is highly recommended to ensure a safe and effective setup​ (RV With Tito)​​ (RV.com)​​ (Renogy)​​ (RVshare)​​ (RV Talk)​.
